VAPOR-BURNER.

SPECIFICATION forming 4part of Letters Patent No. 230,584, dated July 27, 1880.V

Application filed April 5, 1880. (No model.) l

jected a plate, so-called, which extends from a point below the nipplehorizontally,or nearly so, for some distance, and is then curved upward, so as to deect the flame upwardly, and is directed to means for procuring more complete combustion and a better illuminatingflame.

My invention can best be explained and understood by reference to the accompanying drawings, in which- Figure 1 is a longitudinal vertical central section of a plate-burner containing my improvements in their preferred form. Fig2 is a perspective view of the burner without its needle -valve, and detached from the pipes which support it and connect it with the oilsupply. Fig. 3 is a plan of the same with the top plate removed.

A is the usual valve or plug in the coupling B, for regulating the supply of oil which ows to the burner through a pipe screwed into the seat a and communicating with the fluid-reservoir. Screwed on the upper end of the coupling B is the ypacking-tube G, containing wicking or packing, and surmounted, in the usual way, by the burner D, which has a tubular socket or neck, b, fitting l tightly upon and around the upper end of the tube U. At a point on the packing-tube below the burner is placed the usual cup c.

The burner has, in common with other plateburners, the usual plate E, top plate, F, and needle-valve G, for regulating the ow through the nipple or jet-orifice d.

My improvements reside in the several details of construction of the plate E, which will now be more particularly pointed out.

Upon the upper face of the plate I form or attach a transverse bar or rib or projection, e, so placed with relation to the oritice or nipple d that the flame-jet will strike against the said part e. The effect of this is to break up and spread the jet, thereby causing more air to be taken in by or intermingled with the flame than is the case in the ordinary plateburner, and to this extent obtaining better combustion, and consequently a brighter and larger flame.

The rib or projection e is formed at a point between the nipple and the point at which the jet issuing therefrom would otherwisestrike the plate. It not only spreads and breaks up the jet, but also deliects it upward, so as to leave au air-space behind the rib relatively to the direction of' movement ot' the jet, and causing, when the burner is in use, air to enter and pass up between the plate and the flame, which produces more complete combustion, and consequently a more brilliant flame.

In the plate E, just in front ofl the jet orifice or nipple, between the latter and the bar .or raised part e, I form an opening, f, through which air enters, the air for the flame being thus taken through the under side ofthe burner below the flame-jet. This I find is productive of decidedly good results, the air being supplied at a point where it acts with the best effect, especially when the opening is used in conjunction with the bar or raised part e.

The top plate, F, serves as a deflector for the under-draft, and also as a cover to prevent Wind from blowing down through the air-hole The latter serves also as an opening through which the oil from the orifice l can flow down directly into the cup 0.

To obtain greater heat lthicken the top edge of' the outer upwardly-curved part of the plate E, as shown at g, so that the iiame will have room to cover or hug the top edge of the plate against the draft passing up on the back side of' the plate. This feature I find of' advantage. Through the upward ly-curved part of the plate I form a number of' holes, h, extending through from front to rear of' the plate. These holes may be used, whether the plate be thickened at. its upper part or not, and may be formed in the. thickened part, or a little lower down. Their preferred arrangement is shown in the drawings. By this means I greatly incr'ease the heat, inasmuch as the iiame will pass through these holes and burn on the other side, thereby surrounding the top of the metal plate IOO with ame. I have, in effect., two flames, one on each side of the plate, which draw together over the top of the plate and form a single flame, the current of air admitted behind the rib c passingabove the top ofthe plate and oontinuing up between the two parts of the flame until the two merge in one. The result is that I obtain a larger and more brilliant flame than can be obtained in the ordinary plateburner. The upper part of the flame of the latter is of reddish color, and continuously throws olf carbon. In myimproved burnertheilaine is bright throughout its extent, and carbon. if given off at all, is in such minute quantity and so seldom as to indicate very complete combustion.

It is manifest that the form and number of the holes t can be varied, all that is required being an orifice or orifices, whether in the form of a Aslit or a hole or holes of other shape, through which the flame may pass to the other side of the plate. t

I am aware that it has been proposed to use a `grooved or corrugated plate for plate-burners.

I ain also aware that in a vapor-burner it has been proposed to form on each side of the flame-slot in the burner holes for small auxiliary heating-flames, and also to combine with the jet of a vapor-burner a plate curved at its top to form a pocket ovcrhan gin g the jet, with perforations in its top for the passage of the flame. I claim none ot' these things.

Having described my ilwention, what I claim and desire to secure by Letters Patent, is as follows:

1. In plate-burners, the combination, wit-h the nipple, of the plate formed or provided on its upper face, in advance ot' the said nipple, with a transverse rib or bar or raised part projecting above the surface of the plate into and across the path of the flame-jet, substantially as hercinbefore set forth.

2. In plateLburners, the combination, with the nipple, of the plate formed or provided both with a transverse rib or bar or raised part projecting above the surface of the plate into and across the path of the Haine-jet, and with an air-admission opening intermediatev between said rib and the nipple, substantially as hereinbeforeV set forth.

3. In plate-burners, an upwardly-curved deflector-plate formed with Aa transverse rib, bar, or raised part projecting above the face of the plate into and across the path of the flamejet issuing from the nipple, and also provided at its upper end with a iiame'passage extending through the plate from front to rear, substantially as hereinbefore set forth.

4. In plate-burners, the combination of the nipple, the upwardly-curved plate formed or provided with a-transverse rib or bar project ing across the path of the jet from said nipple, and the top plate or shield, substantially as hereinbefore set forth.

5. In plate-burners, the combination of the nipple, the top plate or shield, and the up' wardly-curved plate provided with a transverse bar or rib projecting across the path of the jet from said nipple, and with an air-ad` mission opening at a point between said rib and the nipple, substantially as hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 31st day of March, 1880.
